LINOTYPE-NIACHINE.

Specification of Letters Patent.

Patented Nov. 7, 1905.

Application filed March 6,1905. Serial No. 248,708.

To all whom, it wwtyconccrn:

Be it known that I, PHILIP T. DODGE, o Brooklyn, county of Kings, andState of New York, have invented a new and useful Improvement inLinotype-Machines, of which the following is a specification.

This invention has reference to Mergenthaler linotypemachines andkindred machines wherein a linotype or printing slug is cast in aslotted mold against a line of matricestemporarily assembled against theface of the mold. In this class of machines it is necessary tofrequently change the measure or length of the linotypes or slugsproduced, according to the width ofthe page or column Vof printrequired. This change is effected by altering the length of the slot inthe mold, usually by removing a liner or distance-piece forming one endof the slot and substituting therefor another of different length. Theslugs are expelled from the mold in a forward direction by anejector-slide, which advances from the rear. It is necessary that thisslide shall be of a width substantially equal to the length of the slug,and it is therefore necessary in the existing machines to remove theejector-blade and substitute another of different width whenever achange is made in the length of the mold-slot. This involves theexpenditure of considerable time and necessitates an investment in alarge assortment of ejectors. The aim of my invention is to overcomethese diiiiculties and permit the employment of a single ejector-bladefor delivering slugs of all lengths.

To this end it consists, broadly, in a mold having its liner arranged'to slide endwise without separation therefrom for the purpose ofchanging the length of the mold-slot and of the slugs produced thereinin combination with means for automatically moving this liner to and fr0and retracting it after each casting operation, so that an ejector-bladeof maximum width may be passed through the mold to effect the deliveryof the slug,whether long or short.

I have represented my invention in a form adapted for application to thecommercial linotype-machine of the present day of the generalorganization represented in Letters Patent of the United States No.557,000; but it is to be understood that my invention covers,

broadly, any organization in which a liner is automatically retractedand advanced between each casting operation and the next.

I have limited the drawings herein to those parts which are immediatelyassociated with my improvement, and it is to be understood that theremaining parts may be constructed and arranged as represented in thepatent above referred to or in any other suitable manner.

Referring to the drawings, Figure l is a front elevation of a mold, itscarrying-wheel, and mold adjusting devices, in accordance with myinvention, the mold being in the casting position. Fig. 2 is atransverse section on the line 2 2, Fig. l. Fig. 3 is a perspective viewof the mold-liner and its actuating devices. Fig. 4 is a front elevationof the mold and adjacent parts, the mold being in the ejecting position.with the liner retracted to permit the passage of the ejector. Fig. 5 isa cross-section on the line 5 5, Fig. 4. Fig. 6 is a front elevation ofthe mold and adjacent parts, with the stop for the liner set in aposition different from that in the preceding figures to give a slug orlinotype of different length.

Referring to the drawings, A represents the usual Verticalintermittingly-rotated wheel or disk for supporting the mold or molds.

B represents a slotted mold of the ordinary character fixed rigidly tothe wheel and having its slot or mold proper normally open at the frontand rear sides, so that it may coperate with the line of matrices at thefront and with the mouth of the metal-delivering' pot at the rear. Thismold, which may be otherwise constructed or built up in any suitablemanner, contains a slot or cell in which the slug is cast, and a slidingliner or distance-plate W, the inner end of which forms one end of theslot or cell. Bysliding this liner endwise the length of the slot and ofthe slug or linotype produced therein may be varied at will.

C represents a sliding plate or bar lying between the mold and the diskand guided by a groove in the former. This slide is connected with theliner by a pin b2 or in any other suitable manner, so that when movedendwise it will effect a corresponding movement of the liner. l

D is a spring connected at one end to the IOO disk and at the oppositeend to a stud protruding from the slide C, its tendency being to slidethe liner inward and shorten the mold-slot. l

E isa lever pivoted at e to the mold-wheel and bearing at its oppositeextremity against the inner end of the slide C.

F is a non rotating cam arranged to act against a projection on the faceof the lever E. This cam may be supported in any suitable manner; Abutit is preferably carried on the forward end ofaspindlef, extendingcentrally7 through the huh orjournal of the mold-wheel and secured atthe rear end to a plate f', fastened to a rigid bearing f2, in which thehub rotates. Af ter the casting operation the wheel revolves in thedirection indicated by the arrow, Fig. 1, to the position shown in Fig.4, when it is brought to rest with the mold standing in a verticalposition preparatory to the ejection of the slug.

Gr represents the horizontally-moving ejector-blade arranged verticallyand in position to pass through the mold from the rear in order to expelthe contained slug or linotype H.

The form of the cam F is such that as the lever E is carried around itby the rotation of the wheel A it moves the lever outward, causing it inturn to move the slide C and the moldliner b outward against theiniiuence of spring D, so that when the mold arrives at the ejectingposition (shown in Figs. 4 and 5) the liner is in its outermost positionand the mold-slot of such Width that the ejector-blade G of maximumwidth may pass therethrough and cause the delivery of the slug orlinotype regardless of the length of the latter. The blade may beconstructed and guided as in the ordinary linotype-machines and operatedby the same or any other suitable mechanism.

After the ejection of the slug and the retraction of the ejector thedisk continues its rotation to the original or casting position, andduring this continued movement the cam, releasing the lever, permits thespring D to restore the liner to its inner or casting position.

As the liner is in all cases withdrawn to its extremeposition, it ispossible to use in the machine the one ejector-blade of maximum widthfor the delivery of slugs of all lengths produced in the machine.

In order to adapt the mold to produce slugs of any given length at will,I propose to employ a stop device of any suitable character to limit theinward movement of the liner.

In the form shown the stop device consists of a plate I, having a seriesof transverse teeth adapted to enter corresponding grooves in the lowerside of the mold. The plate may be withdrawn laterally, adjusted endwiseto the desired point, and then rengaged. In Fig. 4 the'plate is shown inposition to permit the casting of a short slug, while in Fig. 6 it isadjusted to arrest the liner at an earlier stage in order to produce aslug of greater length.

I have shown my automatic adjusting devices in one only of the manyforms in which they may be constructed.

I believe myself to be the first to combine with a slotted moldadjustable to vary the length of its slot means for automaticallyeffecting the opening and closing movement of the mold without removingor separating any of its parts and also the first to employ inconnection therewith means whereby the closing movement of' the mold maybe varied at will to control the length of the slug produced therein.

It is to be noted that my automaticallyactuated liner forms afpermanentmember of the mold and that the variation in the length of the slot liseffected without removing or detaching the liner or any other member ofthe mold. This is of great advantage, since it admits of the parts beingaccurately fitted and of the liner being accurately and permanentlyguided within the mold.

Having described my invention, what I claim is- 1. In alinotype-machine, an ejector, and a slotted mold including a permanentattached sliding liner to determine the length of the mold slot or cell,in combination with means for automatically retracting the liner endwise and returning it to its original position, between the successivecasting operations.

2. In a linotype-machine, the combination of an ejector and a slottedmold having a longitudinally-sliding liner mounted permanently thereinto vary the length of the mold slot or cell, means for automaticallyretracting the liner endwise beyond the casting position and returningit thereto, between each casting operation and the next, and adjustablemeans for controlling the advance of the liner.

3. In a linotype-machine, a rotating wheel or carrier, a mold fixedtherein and provided with a sliding member to determine the length ofthe slot or cell, a stationary operating device, and intermediateconnections through which said device controls the adjustment of themold.

4. In a linotype machine, a slotted mold, including apermanently-attached movable member to vary the length of the slot,automatic mechanism acting to move said member, and independentadjustable means to limit the inward movement of the member and therebydetermine the length of the slot.

5. In a linotype-machine, a mold adjustable as to the length of itsslot, a spring tending to close said mold and shorten the slot, meansfor automatically opening the mold to elongate the slot after eachcasting action, and an adjustable ystop device to limit the closing ofthe mold.

6. The combination 'of a mold variable in IOO IIO

10 mum length after each casting action and thereafter closing it to thecasting length, and an ejector of maximum width arranged to cooperatewith .the extended mold.

ln testimony whereof I hereunto set my hand this 3d day of March, 1905,in the pres- I5 ence of two attesting witnesses.
